The company, which went public in November, is expected to launch four new metrics when it reports second-quarter earnings on July 29, the Journal reported, citing people familiar with the matter.
The shift is aimed at changing Twitter's perception as a social network to something similar to Google Inc's YouTube, whose videos are often accessed through other sites.
Tweets are often embedded on other sites or are shown scrolling on television screens, but the company's current metrics do not take those audience into account.
Twitter currently measure its reach using traditional metrics such as monthly active users, monthly unique visitors and timeline views.
The company may now reveal details of how users interact with tweets, including the number of people clicking on links, or those favoriting or retweeting messages, according to the Journal.
Twitter has reported lackluster user and usage growth for the last couple of quarters and its stock price has nearly halved in the last six months.
The company named Anthony Noto as chief financial officer in July, putting a former Goldman Sachs executive who led its IPO last year in charge of its finances.
Twitter's Chief Operating Officer Ali Rowghani departed last month after clashing with Chief Executive Dick Costolo over whether he should continue to oversee product innovation.
Twitter declined to comment on the Journal story.
